osm-extract-validator

Compare the OSM extraction procedures for OSMnx, OSM2GMNS and SharedStreets.

Background

The travel modeling community is embracing OpenStreemMap (OSM) as a source for roadway networks. To use OSM in travel models, the source map needs to be transformed into a routable network. This repository compares the extractions created by several tools, including OSMnx, OSM2GMNS, and SharedStreets.

Instructions

The repository contains the OSM data for Portland, Oregon in both XML and protobuffer formats. Separate Python scripts and corresponding Docker containers are used to extract a database of routeable links from the OSM files using each of the packages.

OSMnx

1. docker-compose up --build osmnx
2. docker-compose run osmnx bash
3. conda activate ox
4. python get-osmnx.py

OSM2GMNS

1. docker-compose up --build osm2gmns
2. docker-compose run osm2gmns bash
3. python get-gmns.py

SharedStreets

1. docker-compose up --build sharedstreets
2. docker run -it --rm sharedstreets shst extract usr/node/nw_pdx.geojson --out=usr/node/shst.geojson --metadata --tile-hierarchy=8 --tiles
